ANCHORING FLANGE. i

Application filed September 4, 1926. Serial No. 133,523.

The object of this invention is to provide an improved metallic anchoring flange for anchoring the edges of stucco or plaster coats to walls and prevent their breaking loose therefrom.

Another object of this invention is to so construct this metallic flange that it will drain the water from the edge of the stucco or plaster finish of the wall.

These and other objects of this invention will be fully illustrated in the drawing, described in the specification and pointed out in the claims at the end thereof.

In the accompanying drawing:

Figure 1 is a vertical sectional view of a section of a wall having a .stucco or plaster coating applied to the outside with the lower edge of the coating anchored thereto by means of my improved metallic anchoring flange.

Figure 2 is a. detail perspective view of a shortlength of the improved metallic anchoring flange.

Figure 3 is a detail perspective view of a slightly modified form of the anchoring flange.

In the several figures of the drawing like reference numerals indicate like parts.

In the application of a stucco or plaster coating to walls the lower edge of the coating generally breaks away after it has been exposed to the weather for a certain length of time. This may be due to the shrinkage of the coating or the deterioration of the lower edge of the coating caused by water or moisture collecting thereon without being properly drained therefrom, or it may be due to a combination of both these causes.

The anchoring flange forming the subject matter of my present invention serves to both anchor the edge of the stucco or plaster coating to the wall as well as drain any water or moisture that may collect thereon. As illustrated in the figures-of the drawing, the anchoring flange is rolled or bent in a continuous strip of metal and has a flat vertical face 1 at the top which is adapted to be placer. against the side of the wall. Holes 2, 2 are provided in this base so that nails or screws can be inserted therethru to fasten the base to the wall. At the bottom of the base 1 the anchoring flange is bent outwardly ant slightly inclined downwardly to form he outwardly projecting supporting base 3 for the stucco or plaster. At the outer end the supporting base 8 is bent back and inclined downwardly forming a horizontal V shaped channel 4 below the supporting base 3. At the bottom of the anchoring flange is formed a small outwardly curved flange 5 which is adapted to deflect the water from the wall as will presently appear. As illustrated in Figures 1 and 2 the slightly inclined supporting base 3 of the anchoring flange is corrugated and a series of holes 6, 6 is provided therein. The anchoring flange is fastened to the wall by means of nails or screws driven thru the holes 2. 2 in the flat vertical base 1 and is so positioned thereon that the supporting flange 3 and the V shaped channel 4 underneath it will be located at the lower end of the stucco or plaster coating. In this way the outer end of the supporting flange will provide a finished edge for the coating after it has been applied to the wall. After the anchoring flange has been fastened to the wall as illustrated in Figure 1 the metal or wood laths 7 are fastened to the wall and the stucco or plaster coating 8 is applied on top of them. When the stucco or plaster coating is applied to the anchoring strip it flows thru the holes 6, 6 into the V shaped channel 4 and partially or wholly fills this channel. After the coating has hardened the stucco thus trapped in the channel 4 remains connected thru the holes 6, 6 with the lower edge of the coating resting on the supporting flange. In this way the lower edge of the stucco 0r plaster coating resting on the supporting flange 3 is firmly anchored to the anchoring flange so that it cannot shrink away from it.

As the corrugations in the supporting flange are also filled by the stucco or plaster coating the elongated ridges formed between them serve to hold the lower edge of the coating from breaking away from the side of the wall. After the coating has been applied water or moisture collecting on the lower edge thereof drains off on the rearwardly inclined exposed outside of the V shaped channel forming the bottom of the anchoring flange. At the inner end of this bottom of the anchoring flange the out" wardly curved deflecting flange 5 serves to deflect the water draining from the bottom of the anchoring flange away from the wall so that it drips into space and keeps the wall underneath the anchoring flange dry. In this way no moisture can accumulate within the anchoring flange nor is any moistureallowed to enter behind or below the stucco Ill) coating so that the edge of the stucco coating 'annot deteriorate by the action of moisture especially in freezing weather in which the ice resulting from moisture will brea k up the lower edge of the stucco or plaster coating.

In the modification of the anchoring flange illustrated in Figure 3 the corrugations of the supporting flange 3 are replaced by the flanges 9. struck up from the holes 6, 6. These flanges surround each of the holes and project into the edge of the stucco or plaster coating so as to prevent the coating from breaking away from. the wall after it has hardened to, the anchoring flange.

I claim;

1. An anchoning flange for the lower horizontal edge of stucco and plaster coatings comprising a metal base strip, a triangular hollow supporting ledge having holes in the top thereof projecting from said metal base strip and an outwardly curved flange on the underside of said supporting ledge and atthe inner end thereof.

2. An anchoring flange for the lower horizontal edge of stucco and plaster coatings comprising a metal base strip, a triangular hollow supporting ledge having holes in the top thereof projecting from said metal base strip, upwardly projecting ridges provided in the top of said triangular supporting flange.

In testimony whereofl aiiix my signature.
